Chapter 6 Chemical bonding / VESPR review

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their valence shell, achieving stability.

Front

What is an alloy?

Back

An alloy is a mixture of two or more elements, where at least one is a metal, designed to enhance certain properties.

Front

Which type of bond involves an unequal sharing of electrons?

Back

Polar covalent bond.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where two atoms share electrons equally, resulting in no charge separation.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the molecular geometry of BF3?

Back

BF3 has a trigonal planar molecular geometry.

Front

How many pairs of electrons are shared in a nitrogen molecule (N2)?

Back

Three pairs of electrons are shared in a nitrogen molecule.

Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is the significance of VSEPR theory?

Back

VSEPR theory (Valence Shell Electron Pair Repulsion) is used to predict the geometry of individual molecules based on the repulsion between electron pairs.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.
